Supporting the Future of Farming 7 year research programme
$9.75 million from Primary Growth Partnership
Matched dollar for dollar by Ballance
Additional $12.5 million in resourcing
Aim: higher production with a lighter environmental footprint
![Page 4: Nutrient management issues and initiatives 2013 Deer Industry Conference James Parsons](https://reader035.vdocuments.mx/reader035/viewer/2022062816/568167cd550346895ddd1ee9/html5/thumbnails/4.jpg)
The challenges
Water quality
Nutrient losses
Rising on-farm costs
Trends towards tighter regulations affecting farming
Consumer demand for more sustainable food production
![Page 5: Nutrient management issues and initiatives 2013 Deer Industry Conference James Parsons](https://reader035.vdocuments.mx/reader035/viewer/2022062816/568167cd550346895ddd1ee9/html5/thumbnails/5.jpg)
Goals
Improve plant nitrogen use efficiency of fertiliser nitrogen
Improve nitrogen efficiency and reduce nitrogen losses within the farm system
Improve nutrient use efficiency and nutrient recovery from animal effluents
![Page 6: Nutrient management issues and initiatives 2013 Deer Industry Conference James Parsons](https://reader035.vdocuments.mx/reader035/viewer/2022062816/568167cd550346895ddd1ee9/html5/thumbnails/6.jpg)
Goals
Improve plant phosphorus use efficiency of fertiliser and soil phosphorus
Cost effective solutions to decrease phosphorus losses from the farm system
Decrease soil accumulation and/or plant uptake of contaminants in phosphorus fertilisers
![Page 7: Nutrient management issues and initiatives 2013 Deer Industry Conference James Parsons](https://reader035.vdocuments.mx/reader035/viewer/2022062816/568167cd550346895ddd1ee9/html5/thumbnails/7.jpg)
Goals
New, novel and robust biological fertilisers that enhance nutrient use efficiency
New bio-pesticides for effective and targeted control of pasture and crop pests

SustaiN Green
•A great product with a well proven active - agrotain (NBPT)
•Strong underpinning science internationally
•Proven to:- Reduce ammonia loss (in NZ on average by about 50%)- Reduce greenhouse gas losses- Increase pasture response
•Current work focusing on determining the magnitude of ammonia loss from urea, as influenced by timing and amount of rainfall following application

•NZ trial work shows typically 10-20% N applied lost to volatilisation
•Range 0%-42% of N applied

Cropzeal DAP boron boost
•A new compound fertiliser – unique to Ballance•Nitrogen, phosphorus and boron all contained in one granule•Ideal starter fertiliser for brassica crops in particular
![Page 13: Nutrient management issues and initiatives 2013 Deer Industry Conference James Parsons](https://reader035.vdocuments.mx/reader035/viewer/2022062816/568167cd550346895ddd1ee9/html5/thumbnails/13.jpg)
Cropzeal DAP boron boost
•More even distribution of boron over paddock = greater plant availability of boron•No segregation, no dust
DAP + granular boron
Cropzeal DAP boron boost

OVERSEER
•A really useful tool for farmers to help understand how changes in management or different land use affects fertiliser requirements
•Assists development of more ‘site-specific’ fertiliser recommendations
•Increasing nutrient use efficiency
•Reducing wastage
•Greater profitability
•Interpretation…
